In the pretreatment process, iron ore fines are ground into finer size, suitable for green ball formation. Dry or wet grinding process is adopted for grinding the iron ore fines. In dry grinding process, equipment drier, ball mill, cyclones/bag filters, hot air generator recirculation fan, air slide, bucket elevator etc. are required. In ...

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell. Grinding tests were carried out with the samples of ...

Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder ...
